摘要
目的探讨基于分子筛技术在高原地区建立的富氧环境对人体生理指标,包括心率(HR)、血氧饱和度(SpO2)以及工作效能的影响。方法在海拔3 680 m的高原环境中,嘱受试者在普通帐篷内休息8 h,用Philips MP20多参数检测仪监测40名受试对象在静息状态下的HR与SpO2,与此同时,检测受试者的工作效能(主要包括数字运算和图案匹配两个项目)得分。之后,利用分子筛式制氧机向半密封式帐篷内供氧,建立氧浓度为27%的富氧环境,让受试者在富氧环境中休息8 h后,静息状态下监测40名受试对象HR,SpO2以及工作效能的测量得分。对比两次测量结果,从而确定高原富氧环境对急进高原人HR,SpO2以及工作效能的影响。结果在高原富氧环境中休息后,受试者SpO2以及工作效能的测量得分显著增高(P<0.05),HR显著降低(P<0.05)。结论高原富氧环境能有效提高人体的SpO2以及工作效能,降低急进高原人群的HR,促进急进高原人群的高原习服过程。
Objective In the high altitude environment, we investigated the influence on human pulse oxygen saturation （SpO2） and heart rate （HR）, working performance score by the oxygen enriched environment which was developed by molecular sieves sciences and technology. Methods We asked the subjects to have a rest in a normal tent for 8 hours after they just arrived at the altitude of 3 680 m, then we monitored the SpO2, HR and working performance score of 40 subjects. After that, we built an oxygen enriched environment by the tent and molecular sieve oxygen generator, the oxygen concentration of this oxygen enriched environment was about 27%, then we asked the 40 subjects to have a rest in this oxygen enriched environment for 8 h, then we monitored the subjects＆#39; SpO2, HR and working performance score and compared the results of all the data before and after take a rest in the oxygen enriched environment in order to study the effects of oxygen enriched environment on SpO2, HR and working performance at high altitude. Results After taking rest in the oxygen enriched environment, all the subjects＆#39; SpO2 and working performance score increased significantly （P 〈0.05）, and the HR decreased significantly （P 〈0.05）. Conclusions The oxygen enriched environment is effective to increase the SpO2 and working performance score, and decrease HR at plateau.
